Change log:

   * Bugfix: race condition in the fair implementation of ReentrantLock
     caused it to occassionally cause IllegalMonitorState exceptions.
     Non-fair implementation was not affected, however, classes that
     depend on fair reentrant locks, namely: fair ArrayBlockingQueue,
     fair SynchronousQueue, and PriorityQueue, were affected. Thanks to
     Ramesh Nethi for reporting this bug and helping to track it down.
   * Testing: backport has been stress-tested using the "loops" tests
     (courtesy of Doug Lea and the JSR 166 Expert Group). The tests are
     included in the development source bundle.

The "loops" tests thoroughly evaluate behavior and performance of 
various types of locks, queues, maps, futures, and other API classes, 
under various conditions (contention etc.) and circumstances, including 
cancellation. The backport has withstood days of testing on Windows XP, 
Linux, and Solaris (SMP), running up to 400 concurrent threads.
